Application led August 12, 1918. Serial No. 249,562.

To all whom it may concern:

Be it known that I, EDWARD G. CARR, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee, and State of Wisconsin, have invented certain new and useful Improvements in Construction Cars, of which the following is a speci'- iication, reference being had to the accompanying drawing, forming a part thereof.

This 1nvention relates to construction cars and the object of the invention is to improve the construction of such cars in the manner to be hereinafter described and claimed.

Referring to the vdrawings which accompany this specification and form a part hereof, which drawings illustrate an embodiment of this invention, and on which drawings the same reference characters are used to designate the same parts wherever they may appear in each of the several views, Fig. 1 is a side elevation of the car; Fig. 2 is a plan view of the car with the receptacle removed; Fig. 3 is an end elevation of the car, parts being shown in section; and Fig. 4 1s a cross section of the car taken on the line 4-4 on Fig. 1, looking in the direction indicated by the arrows.

Reterrin to the drawings, the reference numeral 1 esignates the body frame which is suitably supported by springs through which the weight is transmitted to the wheel axles. The body frame 1 may be constructed from channel hars, as illustrated by the drawings, or in any other suitable or preferred manner, and isprovided with elevated cross members 2 and 3 carried by supports 4, 5, 6 and 7. Horns 8 may be provided to serve as side stakes and planks, timbers and other materials can be transported by placing them on the cross memers 2 and 3. lf a dat car is desired, planks can be laid on the cross members 2 and 3 to form a floor. Special draft gear is provided so that a plurality of cars can be coupled and operated as a train. Draw heads and buders 9 and 10 are pivotally connecte pivots 11 and which pass loosely through Each draw bar is rovided and a lock nut draw bar 13 is surrounded by the spring 18 and the washers 19 and 20 and the draw bar 14 is surrounded by the spring 21 and the washerss22 and 23.. The washer 19 bears 12 to draw bars 13 and 14 ashackle 15.

with a nut 16 rockers can mesh to prevent 17 within the shackle 15. The' against the stem of the draw head and buffer 9 and the washer 22 bears against the stem of the. draw head and buffer lO. The washer 2O bears against stops 24 and 25 secured to the longitudinal members 26 and 27 of the body frame 1 and the washer 23 bears against the stops 28 and 29 secured to the same members. With this construction there is no tendency to pull a bod)7 frame apart as the pull is exerted from draw head directly to draw head through out a train. A pull upon the draw head 9 Ymoves the car by compressing the spring 21 and a pull upon the draw head 10 moves the car by compressing spring 18. A push or bump against the draw and butter head 9 compresses spring 18 and a push or bump against the draw and buffer head 10 compresses spring 21, so that a car in a train is protected by two springs from bumps.

The car is provided with a receptacle 3() which may be removed and replaced or used as a dump car body. The receptacle 30 is provided with rockers 31 and 32 which are adapted to rest upon the cross members 2 and 3 and the cross members are provided with holes 33 with which pins 34 on the displacement of the receptacle. When the receptacle is in an upright position, one of the pins 34 on each rocker projects vertically into a hole 33 in a cross member so that the receptacle can be lifted oii vertically. Studs 35 and 36 are provided for a grapple or a sling for lifting the receptacle and a jaw member 37 embraces a latch 38 vertically to prevent the receptacle from being rocked or tipped. This construction permits the receptacle to be removed by a direct lift and to be replaced by being lowered directly into position. The latch 38 is pivoted to the body frame and extends outwardly through a guide and sto plate 39 and its inner end is heavy enoug to keep the outer end raised. Pressure on the outer end o the latch 38 will depress it far enough to be free of the jaw member 37 and the receptacle can then be rocked or tipped on the rockers 31 and 32 as a dump car. The reference numeral 390 designates a catch for a latch on a lifting grapple (not shown).

The top of the receptacle is illustrated as strengthened and stiiened by angle iron 40 and a container 41 may be placed in the receptacle as a partition and securely clamped en vat any selected position by clamps 42. The combined receptacle and container afford means for holding three parts of materials as, for exam 1e, crushed stone, sand and cement for ma ing concrete. By placing the container in a selected position one end of the receptacle can be filled with a certain quantity of sand and the other end of the receptacle can be filled with the proper proportion of crushed stone While the cement is placed in the container. The receptacle thus becomes automatically a measuring device and dispenses with a separate measuring of the sand and stone contents of concrete. If desirable the capacity of the container can be made proportionate to the cementl content but, as cement is usually contained in bags for ordinary work, the container should be made suliciently large, in proportion to the receptacle, to hold the greatest proportion of cement used in mixtures according to the capacity of the receptacle for stone and sand. Any form of cover 43 may be provided to cover the container water tight and loaded cars can be allowed to stand over night or during a shower or rain without alecting the cement. The container, when used for cement, should be made water tight but the receptacle need not be made water tight where the sides are joined to the ends so any water which gains access to the receptacle can drain off. The

container need not make a tight fit with the bottom of the receptacle and water can flow to the end of the car which happens to be lower. If desired, holes 44 can be made in the bottom of the receptacle at points ordinarily covered by the container and if the receptacle is used without the container for fine material these holes can be readily plugged. The cover 43 can be dispensed with and a tarpaulin or other suitable cover.

can be placed over the receptacle and container whennecessary or des1rable.

The rockers 31 and 32 are made with cylindrical surfaces to roll upon the cross members 2 and 3 and the horns 8 are shaped to the ends of the rockers and serve as stops, when the receptacle is used as a dump car body, to prevent the receptacle from being rolled off from the cross members 2 and 3.

What is claimed is:

The combination with the body frame of a car, of a receptacle provided with rockers, the body frame bein provided with cross members to support te rockers, a latch and a jaw member located under the receptacle for vertical engagement or disengagement with respect to each other, one being secured to the receptacle and the other being secured to the car body frame.

In Witness whereof I hereto ailix my signature.

EDWARD G. CARR.
